Aside from the fact that this movie was not as good as the first two, despite the 3D effects . . . .

It did have a good message . . . .

However, it had one instance of bad astonomy:
"It [bouncing off the target] will shoot you to the dark side of the Moon."
But, I now finally have a pair of 3D glasses for those 3D space pictures! =D>

(Now, if I can just find where those pictures are posted. . . .)
